This patchset introduces a basic support for DELTA multi-format video
decoder of STMicroelectronics STiH4xx SoC series.
DELTA hardware IP is controlled by a remote firmware loaded in a ST231
coprocessor. Communication with firmware is done within an IPC layer
using rpmsg kernel framework and a shared memory for messages handling.
This driver is compatible with firmware version 21.1-3.
While a single firmware is loaded in ST231 coprocessor, it is composed
of several firmwares, one per video format family.
This DELTA V4L2 driver is designed around files:
- delta-v4l2.c : handles V4L2 APIs using M2M framework and calls decoder ops
- delta-<codec>* : implements <codec> decoder calling its associated
video firmware (for ex. MJPEG) using IPC layer
- delta-ipc.c : IPC layer which handles communication with firmware using
rpmsg
This first basic support implements only MJPEG hardware acceleration but
the driver structure is in place to support all the features of the
DELTA video decoder hardware IP.
This driver depends on:
- ST remoteproc/rpmsg:
- https://lkml.org/lkml/2017/1/31/389: remoteproc: st: add virtio_rpmsg
support
- https://lkml.org/lkml/2017/1/31/415: virtio_rpmsg: make rpmsg channel
configurable
- ST DELTA firmware: its license is under review. When available,
pull request will be done on linux-firmware.

version 6
- update after v5 review:
- rework configuration in order to build driver only if at least
one decoder is selected.
version 5
- update after v4 review:
- fixed warning in case of no decoder selected in config
- fixed multiple lines comments
- dev_info changed to dev_dbg for summary trace (from HVA driver review)
version 4
- update after v3 review:
- "select" RPMSG instead "depends on"
- v4l2-compliance S_SELECTION is no more failed
till sync on latest v4l2-compliance codebase
- sparse warnings fixes
version 3
- update after v2 review:
- fixed m2m_buf_done missing on start_streaming error case
- fixed q->dev missing in queue_init()
- removed unsupported s_selection
- refactored string namings in delta-debug.c
- fixed space before comment
- all commits have commit messages
- reword memory allocator helper commit
version 2
- update after v1 review:
- simplified tracing
- G_/S_SELECTION reworked to fit COMPOSE(CAPTURE)
- fixed m2m_buf_done missing on start_streaming error case
- fixed q->dev missing in queue_init()
- switch to kernel-4.9 rpmsg API
- DELTA support added in multi_v7_defconfig
- minor typo fixes & code cleanup
version 1:
- Initial submission
